@ljpp I implemented what you suggested, and it simply doesn’t work. Not even a little bit.
I followed this article to try to implement something like the example. See this result, where I’ve included some debugging to show what the ins element’s inline-style attribute contains when the adplugin renders it:
Here are my settings:
Notice the final result after AdSense has finished its work has a fixed height of 280px, replacing the 90px that the initial ins style had. And AdSense didn’t even find an ad to show, but decided to make the div bigger anyway. 
And anyway, these new settings don’t streamline the AdSense settings, they add a lot more that are even more confusing and don’t actually let you control the sizes with the new way that responsive ads work.
